Christians in Russia won’t be allowed to email their friends an invitation to church or to evangelize in their own homes if Russia’s newest set of surveillance and anti-terrorism laws are enacted.

The proposed laws, considered the country’s most restrictive measures in post-Soviet history, place broad limitations on missionary work, including preaching, teaching, and engaging in any activity designed to recruit people into a religious group.

To share their faith, citizens must secure a government permit through a registered religious organization, and they cannot evangelize anywhere besides churches and other religious sites. The restrictions even apply to activity in private residences and online.
